It will be apparent that water may readily return from the steam chamber QG to the water space l5 through the apertures 3Q, therebj7 providing for constant circulation. The hot gases and products of combustion will be carried ofi' through the uptake flue 19 after passing through the flues 28 and the chamber 18.

It is to be understood that any suitable number and arrangement of water tubes 2T and flues 28 may be provided, and also that the number and arrangement of crown sheets may be varied without departing from the spirit of the invention, the scope of which is limited only by the terms of the appended claims.

I claim:

l. In a boiler, a shell, a plurality of spaced superposed walls arranged within and secured to said shell to deine therewith alternate water spaces and heat spaces, water tubes secured to said walls in such manner as to establish communication between said water spaces, a water jacket having an inlet, said jacket being in direct communication with each of said water spaces, and fines secured to said wall in such manner as to establish communication between said heat spaces.

2. In a boiler, a shell, a plurality of spaced superposed walls arranged within and secured to said shell to deline therewith alternate water spaces and heat spaces, water tubes secured to said walls in such manner as to establish communication between said water spaces, a water jacket having an inlet, said jacket being in direct communication with each of said water spaces, iiues secured to said walls in such manner as to establish communication lbetween said heat spaces, means in communication with the lowermost of said llues to issue heated gases thereto, and uptake means in communication with the uppermost lues.

3. In a boiler, a water acket having a vertical inner tubular wall, a plurality of transversely arranged crown sheets secured along their edges to said wall to define therewith alternate water spaces and heat spaces, said wall having apertures to allow water to enter said water spaces from said jacket, vertically extending means establishing communication between said water spaces, vertically extending means establishing communication between said heat spaces, and a steam chamber having outlet means in communication with the uppermost one of said water spaces.

4. In a boiler, a water jacket, said jacket having a combustion chamber in its lower end, a plurality of superposed crown sheets arranged above the combustion chamber and secured to said jacket to define therewith water spaces, a steam space and heat spaces, said water spaces and steam space being in communication with said jacket, tubes establishing communication between said water spaces and steam space, steam outlet means for said steam space, water inlet means for said jacket, uptake means, and lues supported by said sheets establishing communication between said combustion chamber, heat spaces and uptake means.

5. In a boiler, a. water jacket having an inner tubular wall, a plurality of transversely arranged crown sheets secured to said wall to deiine therewith wat-er spaces and heat spaces, said wall having apertures to allow water to enter said water spaces from said jacket, means establishing communication between said water spaces, means establishing communication between said heat spaces, and outlet means in communication with the uppermost one of said water spaces.

6 In a boiler, a structure having a cylindrical inner wall forming a water chamber, a plurality oli' conical walls secured to said inner wall to define therewith water spaces, a steam space and heat spaces, said water spaces and steam space being in communication with the interior of said chamber, tubes establishing communication between said water spaces and steam space, steam outlet means for said steam space, water inlet means for said chamber, and iiues supported `by said conical walls establishing communication between said heat spaces.
